From a small online business perspective, Evolve Pay-as-you-transact is the sensible decision, as advertised. The moment you are dealing in cash, Evolve 35 has you covered, obviously as you grow you will 'upgrade' the business checking account.
For me, Evolve Pay-as-you-trasanct. It meets my requirements and I won't exceed the Evolve 35 rate. For others, given normal business conditions the best start option would be Evolve 35, but all these Evolve accounts are more the same with the exception being cash handling.
For those who elect to employ themselves in any capacity, Evolve Zero is the logical choice, especially catered to small traders or low volume high turnover online shops (which would take the most advantage) limited to R5 mil annual turnover.
